We have often being told that there are different personalities to our hoggies, but found this description today which I have not come across before.
"Loners"
These hedgehogs are perfectly content to be left alone. They are happiest in their cage at night, running around without being bothered. While they likely won't be totally offended by being handled, they much prefer to keep their own schedule and regard you as the "food, water, and clean-cage giver" only.
A hedgehog's personality may depend on several factors. The main contributor would be handling. A hedgehog that is used to being gently handled, frequently, is often far more friendly than one that is never handled, or is handled with gloves, or in an intimidating manner. The hedgehog's mother personality likely contributes to how comfortable the baby is with humans as well.
